Description

9(Z),11(Z)-Conjugated Linoleic Acid Methyl Ester is a high-purity methyl ester derivative of a specific conjugated linoleic acid (CLA) isomer. This compound serves as a critical intermediate and reference standard in nutritional, pharmaceutical, and biochemical research due to its defined isomeric structure. It is essential for manufacturers and R&D laboratories focused on developing nutraceuticals, studying lipid metabolism, or producing high-value specialty chemicals.

Application

• Nutraceutical & Dietary Supplement Research: Used as a pure reference standard and a key intermediate in the development of CLA-based health supplements targeting weight management and metabolic health.
• Pharmaceutical Intermediate: Serves as a building block for the synthesis of more complex bioactive molecules and prodrugs in medicinal chemistry.
• Biochemical & Nutritional Studies: Acts as a precise substrate or standard in research investigating the mechanisms of action, bioavailability, and health effects of specific CLA isomers.
• Analytical Reference Standard: Essential for the calibration of analytical equipment (HPLC, GC-MS) to ensure accurate quantification and identification of CLA isomers in complex matrices like oils and biological samples.
• Specialty Chemical Synthesis: Utilized as a starting material for producing customized esters, derivatives, or conjugates for advanced material science and cosmetic applications.
• Food Science & Lipid Chemistry: Employed in studies on lipid oxidation, flavor chemistry, and the development of functional food ingredients with improved stability profiles.
